The polishing robot can serve the polishing work and realize the fully automation for obtaining much higher polishing efficiency and well-proportioned surface quality which attracts many researchers’ attention. In this reviews, the research status of the polishing robot are summarized. Twenty-eight articles which published these years about the polishing robot are introduced in brief. The robot system for complex surfaces polishing, automation of polishing process for a cavity surface, intelligently automated polishing abrasive polishing, the CAD/CAM-based position/force controller for a mold polishing robot and so on are reviewed. More research on an effective gasbag polishing technique based on the novel spinning-inflated-gasbag polishing tool, which can obtain well-proportioned quality surface and high polishing efficiency is a potential one. Investigations of the polishing robot will be helpful for the readers understand the robotic polishing.
